#nixos enter to followfor fact you can just rebuild into a clean state at any moment. I also share configs between 2 linux devices and 2 mac devices. Initially started with hyprland, but eventually switched to kde plasma. Nixos without LLM's would have been a pain tho, so would definitely recommend using one.
@tel: I've been leaning hard on NixOS in my latest attempt at a linux desktop box and have been really enjoying it.
